Jimmy, while wearing a Superman costume, attends the launching of an engineless rocket into outer space by Superman. To get a scoop, he sneaks aboard to take photos, and ends up traveling through space. When he crash-lands he finds that he now has super-powers and can live out his super-fantasies. But he can't maintain a secret identity because everyone calls him Jimmy Olsen.

After carelessly almost losing his signal watch and getting chewed out by Superman, Jimmy falls asleep and hides the watch in his sleep. Now he has to figure out how to summon Superman without the watch.
